There is nothing more uncertain in life than life itself. Think of it; we can be here today and tomorrow we are gone. And no one, but no one has any control over life. The brevity of life cannot be denied by anyone, because mortal man can die at any time.
The future is not guaranteed to anyone. The Bible tells us about the uncertainty of life: “You do not know what tomorrow will bring. What is your life? For you are a mist that appears for a little time and then vanishes” (James 4:14). The Bible likens life to a mist, which does not linger indefinitely.
The hymn writer, Isaac Watts, got it absolutely right when he wrote the following:-
Bears all its sons away;
They fly forgotten as a dream
Dies at the opening day.
—Isaac Watts, 1674-1748
In consideration of God and mortal man, Moses acknowledges that God is eternal and faithful. He prayed: “Lord, you have been our dwelling place in all generations. Before the mountains were brought forth, or ever you had formed the earth and the world, from everlasting to everlasting you are God. You return man to dust and say, “Return, O children of man!” For a thousand years in your sight are but as yesterday when it is past, or as a watch in the night” (Psalm 90:1-4).
The text seems to be telling us that God who is from everlasting to everlasting is the dwelling place of His people—in all generations. This is most comforting for us to be aware of; even in the uncertainty of our lives.
Moses also mentions human life expectancy at 70 or up to 80 years: “The years of our life are seventy or even by reason of strength eighty; yet their span is but toil and trouble; they are soon gone and we fly away” (Psalm 90:10). Toil and trouble could mean difficulties and hardships.
In view of life’s fleeting years, Moses also asked God: “So teach us to number our days that we may get a heart of wisdom” (v.12). The point is we must seek God’s wisdom in all that we do, so that He will lead, guide, and direct us.
It is not a man who determines his own life-span. Rather, it is God, the Sovereign Creator of the universe, who placed man on the earth and determined how long he will live. Here’s what Job said about the uncertainty of life.
“Man who is born of a woman is few of days and full of trouble. He comes out like a flower and withers; he flees like a shadow and continues not. And do you open your eyes on such a one and bring me into judgment with you? Who can bring a clean thing out of an unclean? There is not one. Since his days are determined, and the number of his months is with you, and you have appointed his limits that he cannot pass” (Job 14:1-5).
Job sees life like a flower that appears and withers. And like a shadow that continues not. A flower with its delicate structure, colorful beauty, and appeal is short-lived. A shadow only lasts for a limited period of time. When the object moves, the shadow completely disappears.
The Apostle Paul was fully conscious that he was approaching the end of his life when he said: “the time of my departure has come.” In his readiness to go, the Paul confidently expressed:
“For I am already being poured out as a drink offering, and the time of my departure has come. I have fought the good fight, I have finished the race, I have kept the faith. Henceforth there is laid up for me the crown of righteousness, which the Lord, the righteous judge, will award to me that Day, and not only to me but also to all who have loved his appearing” (2 Timothy 4:6-8).
It seems obvious Paul realized his life was “a mist that appears for a little time and then vanishes.” He was filled with gratitude to God for enabling him to finish the race and keep the faith to the end of his life. This is most inspiring for believers today.
In summary, let’s consider and do what Paul is exhorting here. He says, “Look carefully then how you walk, not as unwise but as wise, making the best use of the time, because the days are evil. Therefore do not be foolish, but understand what the will of the Lord is” (Ephesians 5:15-17).
Making the best use of the time is most important. There’s no time like the present time. Earthly life will not go on forever. Therefore, let us seize every opportunity to live in a manner conforming with God’s holy Word; being doers of the Word, and not hearers only, deceiving ourselves.
Only what’s done for Christ will last.”
